MACHINERY FOR MANUFACTURING BOLTS.

SPECIFICATION forming part of Letters Patent No. 686,700, dated November19, 1901. Application filed December 27,1900. Serial No. 41,183. (Nomodel.)

To all whom it may concern:

Be it known that I, JOSEPH BARTosIE, a citizen of the United States ofAmerica, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful improvements inMachinery for Manufacturing Bolts; and I do hereby declare the followingto be a full, clear, and exact description thereof, reference being hadto the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in machinery for manufacturing bolts, and relates more particularly to a machinefor forming and finishing heads on bolts.

The invention has for its object the provision of novel means wherebymetal may be fed into the machine of the character described and thehead of a bolt finished therein by the novel mechanism and pulley.

The invention has for its further object to construct a machine of thischaracter that will be extremely simple in its construction and strong,durable, and highly efficient in its operation.

The invention further aims to construct a mechanism of the characterdescribed that is not apt to become out of order and wherein theoperation of the different parts is assured at all times.

With the above and other objects in view the invention consists in thenovel combination and arrangement of parts to be hereinafter more fullydescribed, and specifically pointed out in the claims.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification, whereinlike numerals of reference indicate corresponding parts throughout theseveral views, and in which-- Figure 1 is a side elevation of my improved machine for forming heads upon bolts. Fig. 2 is a longitudinalsectional view thereof. Fig. 3 is a top plan View of the same. Fig. 4 isan end elevation, showing the pawl-andratchet movement of the headoperating the mechanism. Fig. 5 is a vertical sectional View on the line5 5 of Fig. 1. Fig. 6 is a vertical sectional view taken on the line 6 6of Fig. 3 looking in the direction of the arrow.

Fig. 9 is a similar view of the gage.Fig. 10 is a perspective view of the clutch mechanismformingthegrippingmeans. Fig. 11 is a fragmentary vertical sectional view of the die inthe operation of forming a head. Fig. 12 is a perspective view cf theadjusting means regulating the various lengths of bolts. Fig. 13 is aperspective View of the anvil. Fig. 14 is a perspective view of one ofthe dies for forming or finishing the head. Fig. 15 is a side elevationof the finished article.

In the drawings the reference-numeral 1 indicates the base-plate, and 2represen ts standards, upon which `is mounted a crankshaft 3, carryingon one end a driven pulley 4 and at the other end a crank-arm 5, havingconnected thereto a rod 6, to which is pivotally connected at 7 a rod 8,the end of which is bifurcated, as shown at 9, and connected to thebell-crank lever 10, which is pivotally mounted at 11 in the standards2, extending upwardly from the base-plate. To the other end of saidbell-crank lever is pivotally secured at 14 a downwardly-extending rod15, which is connected at 16 to the crank-arm 17, carrying a pawl 18 andoperating the ratchet 19, said crank-arm 17 being rotatably secured uponthe shaft 20, to which is rigidly secured the ratchet-wheel 19. Saidshaft 2O extends through the housing 21 and a bearing 22, secured in thestandard 23, extending upwardly from the base-plate 1. The said shaft 21carries a rectangular head 24, which is rigidly secured to said shaft 21and adapted torotate with the said shaft. This shaft 21 is furtherprovided with a collar 25. The said head 24 is provided with foursidesand carries on each side a clutch-gripping.mechanism which Ainconstruction are alike upon all sides, but

for the purpose of illustration I will only describe in detail one ofthe sides, as shown in Figs. 7 and 1O of the drawings. 'Ihe side facesof the head are provided with a suitable opening having arranged thereina trip-lever 26, said trip-lever carrying a beveled end 27 and a pin 28.A spiral spring 29 is adapted to encircle said trip-lever, the latterbeing seated in the enlarged opening 30, formed in the faces of thehead. A sliding head 31 is pivotally secured at 32 to said trip-leverand IOO carries outwardly-extending arms 33, which are pivotally securedat 34 to the sliding head, the upper arm 33a carrying a grip 35, whichis. adapted to clutch the bolt 36 against the anvil 37, the latte:Ibeing dovetailed, as shown at 38, and is seated in the face of the head.A recess 39 is arranged in the head for the reception of the bolt, andin said recess is arranged a bearing 40 for the reception of thescrew-threaded gage 4l, which operates therethrough, said screw-threadedgage carrying on its end a follower 42, that Will accurately limit andgage the distance to which the bolt is applied in the machine. rIhe headis further provided with an enlarged opening 43 for the reception of theformingdie 44 and the finishing-die 45. These dies are mounted upon arectangular sliding head 46, carrying a bifurcated end 47, to which ispivotally secured at 48 an arm 49, mounted upon the crank portion 50 ofthe crank-,shaft 3.

The reference-numeral 5l indicates the enlarged portion of the housing21, forming a shoulder for the engagement of the beveled' end 27 of t-hetrip-lever 26.

The forming-die is mounted on the upper face of the sliding head andoperates through the yoke 52, the rear end of said forming-die operatingin the bearing 53, rigidly mounted upon the upper face of the slidinghead.

The reference-numeral 54 indicates a retractile spring, one end of whichis securely fastened to the bearing 53 and the other end to the die.This spring serves for normally retaining the dies in the forwardposition.

The reference-numeral 55 indicates a rod extending from one side of themachine to the other and is suitably fastened to the bearing, said rodcarrying screw-threads 56, upon which is mounted the gage 57, said gageforming a table for feeding the mechanism, this gage being provided witha rib 58 for the purpose of accurately placing the material into themachine. The said gage has formed therein a notch 59 for the purpose ofallowing the follower 42 to pass as the head revolves.

The reference-numeral 60 indicates the shields or guards, whichpartially cover the mechanism of the revolving-head and provide a spacefor feeding the material into the said revolving head.

The'operation of my improved machine is as follows: Power beingcommunicated to the driven pulley 4 and communicating movement to thecrank-arm 5 through the crankshaft 3 will tend to rock the be1l-cranklever and communicate motion to the rod l5, thereby transmitting anintermittent rotary movement to the rotating head 24 through the mediumof the pawl and ratchet 18 and 19, the met-al being fed upon theguide-plate into the machine, where the same will be clamped by means ofthe clutch and anvil, as shown in dotted lines in Fig. 7 of thedrawings, the trip-lever 26 being forced inwardly by reason of theshoulder 5l, arranged upon the interior face of the housing.Simultaneous with this operation the arm 49 will tend to slide the headinwardly, the forming-die coming into engagement with the end of thebolt, and with the next revolution of the crank-shaft, as the revolvinghead has been again rotated partially, the nishingdie will come inengagement Wit-h the head and finish the same. In the meantime, however,the next bolt has been inserted in its proper position and is ready tobe finished as heretofore described. As the head revolves to the nextposition the spring 29 will return the clutch mechanism to its normalposition, thereby releasing its grip from the bolt, and the same willdrop to the floor in a finished state, the operation being a continuousone, as the machine is constantly fed by the operator.

It will be understood that the dies may be moved to the different sizesinserted and also that the gage is adjustable in order to accuratelycontrol the various sizes of bolts that may be inserted.

The many advantages obtained by the use of my improved machine will bereadily apparent from the foregoing description, taken in connectionwith the accompanying drawings.

It will be noted that various changes may be made in the details ofconstruction without departing from the general spirit of my invention.
